Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hphr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value (net Hphr/t) from an empirical formula.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().

The standard Bond Rod Mill Work Index test procedure is firstly to stage crush the feed to pass mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond rod mill. A Bond rod mill is by, with wave liners (of a form described by Bond), which runs at 40rpm and tilts as described below.
